Allow the layers copy from external portals

[vjrj]

Currently the creation of common layers in each LA spatial portal is a tedious and time cost effort. With common layers, I mean layers generic that can be used in any LA portal, like world or similar layers.

spatial-service has a copy layers functionality but this is only allowed to auth systems in a local LA portal via an api-key.

It would be interesting to have a central spatial service in the LA community that allows that copy operation to others LA portals without this restriction of with some external or different authorization. This can relief this layer creation task in other LA portals.

The login function in:

spatial-service/grails-app/controllers/au/org/ala/spatial/service/ManageLayersController.groovy

Line 583 in 49af0d8

def copy() {

is the responsible of allowing or not the copy right now.

As this login is used for other layer tasks, it will be nice if this can be deactivated or configured in other way to allow these copy operations. I can send some PR if we agree in some option.

I can create a shared spatial service for this purpose and offer it its use to the LA community, but it will be nice if I can copy first some general layers (for instance from ALA).

Any comment? TIA
